Hardkernel ODROID-M2 Review
Hardkernel ODROID-M2 single-board computer with Rockchip RK3588S2, 8GB or 16GB LPDDR5, 64GB onboard eMMC, PCIe 2.0 x1 M.2 NVMe slot, Gigabit Ethernet, dual HDMI 2.0 up to 4K60 HDR, MIPI DSI.
Hardkernel's compact RK3588S2 board ships with 64GB of onboard eMMC and boots reliably from it, with an M.2 NVMe slot available for extra storage, aimed more at NAS and always-on server builds than general tinkering.
Overview
The ODROID-M2 ships without eMMC or microSD as its primary boot device by default, it's designed to boot directly from the onboard NVMe M.2 slot, giving it far better sustained I/O than SD-card-based boards.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- Compact NAS or home-server builds wanting real NVMe speed
Not for
- Projects needing a full 40-pin GPIO header for sensors/HATs
